STEAM-GENEEA'IING APPARATUS.

Tot clflwhom t may concern:

Be it known that I, lfVrLaEnroncE B. HAM- Mo-Nn, citizen -of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Steam- Generating A paratus; and I do hereby declare the following/to be a full, clear, amd. exact description ofthe invention, such as will enable others skilled in the art to wbichit appertains to make and. use the same; y l 1 i The ainvention relates to anf apparatus or 'system for geneatng steam, and more particularly to a. system in which low` pressure steam is generated andv utilized to drive a low pressureturbine or other motor? for fur- It 'is the object of the invention to provide a system or apparatus which ivillltenable water-to be used as a. means for conveying heatfrom a point 'or locality Where a, heating means is located to a remote point or locality where it is desired .that steam be generated.` That is to sa .it is the object oli-the invention to provi e for locating the heat supplying means and the steam genera tor at points which are remote from each other,vand `for conveying the heat from the heating devices to the generator by the circulation of hot water.

To. thisI end the invention contemplates the provision of a. steam generator which is supplied with Water. through a supply pipe leading-from' a water heating device, and

means for returning the water from the of any `suitable form of device for heatingA generator to the heating device in suchmanner that 'he water in the generator 1s main- 1 tained at a proper level for the generation of steam.

The invention contemplates the provision the hot. water which is supplied to and returns from the generator.

More specifically considered, the invention crmtemplatcs the provision of an accumulator or hot water heater by which the exhaust steam froma motor or other steam usiugdcvicc maybe utilized to heat the water supplied to thc generator, 'and also contemplates the provision 'of a motor whichl may he driven l'rylow pressure steam generated byf heating the water to a comparatively low temperature. Vith this form of Specication o! Letters Patent.

apparatus, power may be economically developed inplaces and under conditions Where the economical development of power would be impractieablewit-h the construction and arrangement of steam enerating apparatus commonly employed. his form of apparatus also enables the waste heat in the exhausts from various steam using -devices to be utilized to generate steam for power or other purposes at points remote from where the exhaust takes place, and enablesthe transmission from the point of exhaust to the place where the steam is to be utilized to' be effected economically and convenientlv and with the use of pipes and ap- Any suitable construction of generator may be employed inA practicing 'the'invention, andany suitable means may be employed for causing the .clrculation -of the 'water through the supply and return pipes between the heater. and generator, and any suitable means may be employed for properly regulating the supply and return in ac oordance with the conditions-under which the lapparatus is being used.

The various features ofthe invention will be readily understood from an inspection of the accompanying. drawings'in whlch 'an apparatus embodyin the various features of the inventlon is illustrated diagrammatically. In these drawings, Figure 1 is a diagrammatig view of the apparatus, and Fi 2 is a detail showing the'manner-of disc arging tli water from the supply pipe into the generator.

As -shown in the drawings, the apparatus comprises a. steam generator 1 which is provided with a steam dome or chamber 2. The

steam chamber ofthe generator communicates through a pipe 3 with a low pressure motor indicated at 4C. As shown, the motor4 is indicated as a turbine, and is provided with a condenser 5, so that it may act eiieiently when supplied with low pressure steam..

lVater heated t0 a temperature suiiiciently high to neratc steam under the low sure which exists in the upper part o the generator is supplied to the generator' through a supply pipe 6, the lowiof water through the pipe being controlled by a'suitable regulating device whichisvindlcated as a valve 7,1 The supplygpipeegpnegts with 25 `pound engine comprising the cylinders 15' "55 The water discharged through the' pipe 19 a pipe 8 which extends through thc general tor, and is provided on its upper side with discharge nozzles 9. The water is discharged through the nozzles 9 against detlectors 10,

and is broken up into spray, so that the generation of steam from the water is facilitated. The water which does not pass into steam collects in the lower part of the generi ator 1l. Thiswater is withdrawn through l0 a return pipe 11, the withdrawal of the water being regulated so tb t the water in the generator is maintained at the proper level. The iiow of water through the return pipeis controlled and regulated by suitable controlling devices indicated as valves 12 and 17 in the apparatus illustrated.

The supply and return pipes connect the generator l with a device for heating the water 4which is supplied to and returned 20 fronrthe enerator. The hot Water heating device in t ie apparatus shown is an accumulator 13 constructed to enable the ivater therein to be heated by exhaust steam supplied'through the exhaust pipe 14 of a comand 15 and a receiver 1,5". As shown, the en ine is supplied with steam from the boilers 16. The heater 13 is located where the heating of the water may be economically effected, as, for instance,l closely adjacent to the engine or other steam using device from which exhaust steam is supplied to The generator 1 and motor 4 driven by the steam coming therefrom are located at any point where it is desired-to enerate power, which oint may be remote rom the place where t e heater is located. In case the generator is' located at a point above the heater, gravity may be depended 40 upon to secure the flow of water through the 'return pipe 11, the rate of ilow being regulated bythe valves 12 and -17 In this case, a pump 18 is provided for securing the -iow of water from the heater 13 through the supply pipe 6. It will of coursebe understood that any suitable devices may be utilized for causing the flow'of water through the pipe 11 as well as through the pipe 6.

The water which returns through the pipe 5911 is discharged from the u per end of a pipe 19 which extends upwit in the heater or accumulator 13, and this water is brought into intimate contact and min led with the exhaust steam supplied throng the pipe 14.

falls into theupp'er tray 200i a series of trays mounted inthe accumulator,- and flows down through ythese' trays so thatits surface is subjected to' the steam within the upper part of the accumulator'. An effective heating of the water within the accumulator is thus secured. The water vwithin the heater thus accumulates heat from the exhaust steam, and the heated'water is transferred, to the generator 1 where it will be trans- Amotor 1.

Having explained the nature and object l of the invention, and described one form of apparatus in which it may be embodied, what I claim is 1. A steam generating apparatus, having, in combination, a steam-generator, a device for healing water to the temperature requisite for generating steam in the generator, 80 supply and return pipes for conveying the heated water from the heater to the generator and returning water from the genen ator to the heater, and means for causing a circulation ot the water through the suppl)r and return pipes tomaintain the water 1 in the generatorlat the proper level for the generation of steam whereby the heat requisite for generating'the steam is imparted to the water at'a point remote fromthe 90 generator, substantially as described.
